小麦镇压对南方来说还是一项新技术。丽水县广大社员,去冬根据麦苗猛发的特点,发扬了敢想敢干的风格,有万亩小麦进行了镇压。据调查,在一定条件下,小麦采取镇压,能促进分蘖,防止徒长和抑制提早抽穗;对增产起了良好作用。茲将调查结果分述如下:1.增加单位面积有效分蘖穗:小麦苗期镇压,地上部生长受到抑制,大量养分集中于分蘖节,促进分蘖迅速萌发,增加早期分蘖;在分蘖末期镇压、能抑制无效分蘖的发生而提高有效分蘖率。丽水县农科所试验结果表明:经镇压的单株有效分蘖达2.3个,有效分蘖率达70%,比不镇压的单株有效分蘖0.34个增加1.96个,有效分蘖率25.5%增加44.5%;
Wheat suppression is still a new technology for the South. Members of Lishui County, go winter according to the characteristics of barley fierce, carry forward the style of daring to dare to dry, wheat mu has carried out repression. According to the survey, under certain conditions, wheat to suppress, can promote tillering, prevent leggy and inhibit early heading; play a good effect on yield. The survey results are summarized as follows: 1. Increasing the effective tiller panicle area: wheat seedling suppression, shoot growth was inhibited, a large number of nutrients concentrated in the tillering node, to promote rapid germination of tillers, increase early tillering; suppression at the end of tillering, can Inhibit the occurrence of ineffective tillers and increase the effective tillering rate. The experiment results of Lishui Agricultural Science Institute showed that the effective tillering rate of the single crop reached 2.3, the effective tillering rate reached 70%, 1.96 more than the effective tillering no - growth 0.34, the effective tiller rate increased by 25.5% and 44.5% respectively.
